This is a single 10sec exposure in the Aussie outback on old consumer gear ( Sony a7iii ) https://www.instagram.com/p/CersLuLBfCz You don’t need multiples, and you don’t need an overly long exposure. | |||||||||||||||||||||||

It sounds like you know what you're talking about until one realizes the earth is spinning. Wide field photos can be shot up to thirty seconds depending on the back and lens. Anything more zoomy than 50mm uncropped you're getting streaks in < dozen seconds. There's a rule of thumb but I don't remember it. Best course of action is to take a video and let a stacking program deal with it, especially if you use a real telescope. Also the Sony a7r have like "150,000 ISO " and iirc cost like $3500 with a kit lens. That's a bit above consumer, but I may have mixed up models. | |||||||||||||||||||||||
